Abstract: 1,160,625. Sanitary napkins. MOLNLYCKE A.B. 4 April, 1967 [28 April, 1966], No. 15290/67. Heading A5R. In a sanitary towel comprising an absorbent core member enclosed within an envelope consisting of a non-woven non-absorbent soft material, the envelope is perforated on that side which is intended to face the body of the wearer and preferably is liquid-tight at the edges thereof and on that side which is intended to face away from the body of the wearer, a wadding-like layer being interposed between the absorbent core member and the envelope. As illustrated in Fig. 1, the towel comprises an absorbent core member 1 enclosed within an envelope 2, a soft layer 3 of wadding being interposed 'between the core member and the envelope on that side of the towel which is intended to face the 'body of the wearer. Situated within the core member may be a liquid-dispersing layer 4 in the form of a thin sheet of cellulose wadding; situated adjacent each side of the core member may be sheets 5 and 6 of cellulose wadding. The absorbent core member preferably consists of dry defibrated cellulose. The envelope may consist either of a fibrous material which has been rendered hydrophobic by special treatment or of a material which itself is hydrophobic without such treatment; the envelope thus may consist of rayon fibres which have been rendered hydrophobic or of a layer of paper which has been rendered hydrophobic and water-repellent by passage through a bath of paraffin. The soft layer may consist of a wadding which allows liquid to pass directly to the absorbent core member but which neither absorbs nor allows lateral transport of liquid within itself; the soft layer thus may consist of rayon fibres or of polypropylene fibres which have been treated to have these properties. Figs. 3 and 4 (not shown) illustrate various sizes, shapes and patterns for the perforations of the envelope. Fig. 5 (not shown) illustrates that such perforations may extend into the edges of the towel.

Title: Improvements in or relating to a hop picking machine
IPC: A01D46/02
Filed: 1949-06-10
Abstract: 685,691. Hop-picking machines. CLEMENS HORST CO., E. June 10, 1949 [March 16, 1949]. No. 15508/49. Class 58. In a hop-picking machine flexible rubber hop-pickers 53, 42, 62, 63 are provided having metallic discs notched around their peripheries to engage and selectively detach the hops from the rest of the vine material, which move through the vines as they travel in undulatory paths through the machine and thoroughly traversing the interior of the vines as well as the superficial parts. As shown the vines are carried through the machine in undulatory paths 31 and 52 by the top and bottom runs 13, 14 respectively of a conveyer, between which an endless conveyer 36 runs in the opposite direction on runners 38 to give a " parallel" course to that of the vines having thereon a series of flexible pickers 42 so adjusted that they are drawn through the vines backwards removing the hops by engaging them in the small notches in the discs. Additional fixed pickers 53, 61, 62, 63 are provided for dealing with the vines on the outside of the runs 13 and 14. Another conveyer 64 with similar pickers thereon is provided for also dealing with the vines on the outside of run 14. The detached material falls through the machine on to a diamond mesh belt 71 the large material being passed out of the machine and the smaller, i.e. hops, passing through the belt over a pair of fishnet type separators 74, 76 on which any leaves, &c.. are held by blast from nozzles 77, 78 when they eventually are discharged into conveyers 79, 80 whereas the hops roll down the belts 74, 76 on to and are removed by the conveyers 81, 82.

Title: Improvements in and relating to apparatus for washing coal or the like
IPC: B03B5/68
Filed: 1930-05-20
Abstract: 355,269. Washing granular materials. DEAN, G. E., 1530, Green Ridge Street, Scranton, Pennsylvania, U.S.A. May 20, 1930, No. 15522. [Class 82 (ii).] Coal or the like to be washed is delivered on to breaking rolls situated in a lateral extension at one end of a separating tank, a shoot being arranged under the breaking rolls to lead the crushed material into the main portion of the separating tank where it is subjected to the action of a deflecting current which separates the constituents of different specific gravities directly on to conveyers which move upwardly from the deep end of the tank and out at the shallow end. Coal is delivered from a shoot 25 into a hopper 24 which leads it to breaking rolls 18 situated in a lateral extension 2 at the deep end of a tank 1 which is shallow at the other end 3 and has an intermediate sloping bottom 4. A shoot 9, the inclination of which can be adjusted by chains 26, is positioned below the rolls 18 and leads the material :into the main part of the tank. On leaving the shoot 9 the material is subjected to the action of a deflecting current produced by air or water under pressure forced through pipes 16 with nozzles 17, the position and inclination of the pipes being adjustable. The deflecting current may be produced by mechanical agitation. The action of the current causes a separation of the materials the heavier particles falling on to a conveyer 10 and the lighter particles on a more distant conveyer 1]. The conveyers have partition plates 13 at their edges to keep the materials on the conveyers, the plates on the conveyer remote from the shoot 9 being preferably perforated. The conveyers which may run at different speeds carry the materials up and out of the liquid at the end 3 of the tank and deposit them in shoots 14 leading to other conveyers. Additional coal may be introduced into the tank at any point without passing through the breaking elements. The breaking rolls 18 are connected by gearing 19, the shaft of one of the rolls passing through a watertight packing in the side of the tank and gearing with a driven shaft 21. Guards 23 extend over the upper outer portions of the rolls 18.

Title: Improvements in or relating to supercharged internal-combustion engines
IPC: F02B33/00
Filed: 1941-12-02
Abstract: 553,795. Pumps. BRISTOL AEROPLANE CO., Ltd., and OWNER. F. M. Dec..2, 1941, No. 15535. [Class 7 (ii)] [Also in Group XXIV] In engines in which supercharging is effected in two stages by means of two continuouslydriven superchargers arranged in series, the first-stage supercharger is driven through multispeed gearing, and when the second supercharger is being used alone to supply the engine, the first supercharger is operated at low speed so as to make up the pressure loss to which the charge is subjected in passing through the first supercharger. Fig. 1 shows the second supercharger 12 driven from an extension 17 of the crank shaft 16 through gearing 26, 28, 32, 33, whereas the first supercharger 14 is driven through a three-speed gear 49, 34, 35, 36. Fig. 3 shows the three-speed mechanism comprising planet wheels 40, 41 mounted on shafts 39 in a carrier 38 and engaging sun wheels 47, 45 carried by coaxial shafts 48, 46, the pinions 41 also engaging an internal gear 42 on the casing 34, which also carries the gear 35. The casing 49 encloses disc brake mechanism comprising discs 55 connected to the shaft 48 arranged at one side of a stationary disc 53, on the other side of which is a disc 59 connected to the shaft 46, the discs 55, 59 being moved axially into or out of contact with the stationary disc by hydraulically-actuated diaphragms 54 and 58 respectively. For low speeds both sun wheels 45 and 47 are released, while for medium speeds the wheel 45 is held against rotation, and for high speeds the wheel 47 is fixed. In low speed, both sun wheels are free and no drive is imparted to the supercharger 14, which thereupon slows down until its speed is reduced sufficiently to cause the planet wheels to drive the sun wheels in a direction which tends to drive a toothed ring 62 through a ratchet 66 at a higher speed than the planet carrier. This causes helical splines 61 to move the ring 62 laterally, thereby bringing helical teeth 63, 64 into engagement and locking the sun wheel 47 to the planet carrier so that the whole gear rotates solid, giving sufficient low speed to the supercharger 14 to compensate pressure loss. When the medium speed is engaged the teeth 63, 64 automatically disengage. In a modification the three-speed gear is replaced by a twospeed transmission as described in Specification 465,612, [Group XXIV]. The gear 26 is driven through a resilient coupling 31 and the supercharger 14 through a centrifugal clutch 37, both as described in Specification 293,713, [Class 7 (ii)].
